Help to choose the right board

[Bergoglio]

Good afternoon,

I need an help to choose the right KC868-A model (I don't want to make a mistake because I must buy 21 pieces....)
My hardware minimum specs :

1. the board must have an ethernet (rj45) port
   
2. min 5 releays NO/NC max load 1 A at 230v
   
3. I must connect to every board n. 4 temp sensors DS18B20
   

What is the best solution ?

Thanks
